How Sophie’s Posthumous (and Final) Album Was Completed

In the early hours of Jan. 30, 2021, the visionary hyperpop producer Sophie was living in an apartment in Athens. To get a better view of the full moon, she climbed up a balcony, but slipped and fell. She was 34, and her death brought an outpouring of appreciation for the ways her sonic vocabulary — pointed, wriggly, blippy synthesizer tones and ultra-succinct hooks — had moved so quickly from pop’s experimental fringe to the mainstream.

In Athens — and before that in Los Angeles and London — Sophie had been working on the successor to her 2018 album, “Oil of Every Pearl’s Un-Insides” and its 2019 remix LP. The new album was so close to completion that Sophie had chosen the full track list. Three years later, Benny Long, her brother and studio manager, has finished it, striving to honor Sophie’s artistic intentions. It will simply be titled “Sophie.”

“There was, at the start, a lot of self-doubt. Can I? Is this going to be possible without her?,” Long said in a video interview from Los Angeles. “But I thought, really, it comes down to, would she want this album to come out or would she not? And she definitely would.”

Sophie left behind many more tracks in progress, some of which are likely to emerge as singles or EPs, or appear on other performers’ albums. But as a guardian of Sophie’s catalog, Long has decided that “this is the last Sophie album,” he said. “This is an album that we had worked on for years. We discussed everything about it — the themes, the track list. So to do another album and put it out as a solo album, it would just feel all wrong.”

“Sophie,” out Sept. 27, is the artist and producer’s most collaborative album. It includes vocals from the songwriters and singers Kim Petras, Bibi Bourelly, Hannah Diamond, Cecile Believe, Jozzy, Big Sister and Liz, as well as the duo BC Kingdom (who have recorded with Solange Knowles). There’s even a spoken-word appearance by the D.J. and producer Nina Kraviz.

Completing the album became a family project for Benny and his sister Emily Long. She studied music law to work with Sophie, and she passed the bar exam two weeks before her sibling’s death. Once Benny resolved to finish Sophie’s album, Emily joined him in making decisions. “Every single day we talk about Sophie and what she loved and the things that would make her happy,” Emily said via a video call from Los Angeles. “We all know why we’re here. We’re all here for her.”
